HYDROXYPROPYL STARCH

Description

Hydroxypropyl starch is a versatile ingredient widely used in skincare and haircare formulations. This modified starch derivative is created by treating natural starch with propylene oxide, resulting in a water-soluble compound with enhanced stability and functionality. Its unique properties make it an excellent choice for various cosmetic applications, particularly in leave-on products and hair styling formulas.

In skincare, hydroxypropyl starch acts as a thickening agent and emulsion stabilizer, improving the texture and consistency of creams, lotions, and gels. It also provides a smooth, non-greasy feel to products, enhancing their sensory appeal. This ingredient has moisture-binding capabilities, helping to maintain skin hydration and creating a protective film on the skin's surface.

For haircare, hydroxypropyl starch is valued for its film-forming and conditioning properties. It can help improve the manageability of hair, reduce frizz, and provide a light hold in styling products. Additionally, it contributes to the volumizing effect in hair formulations, making it a popular choice in dry shampoos and texturizing sprays.

Hydroxypropyl starch is generally well-tolerated by most skin types and is considered safe for use in cosmetic formulations.
